What is the correct way to reference an array element?

• A. $MyArray(index)
• B. $MyArray{index}
• C. $MyArray[index]
• D. $MyArray[index()]

Answer: (C)

The correct choice for referencing an array element is to use square brackets. In many programming languages, including languages like Python, JavaScript, C, and others, accessing an element in an array is done by specifying the index within square brackets. This syntax clearly indicates that you want to retrieve or manipulate the element located at the specified index of the array. Using square brackets is a standard practice across numerous programming languages because it clearly differentiates array access from other operations. The index inside the brackets indicates which specific element to retrieve, starting from zero in most programming languages. While other notations exist in some contexts, they do not align with the common syntax for array access in most languages, making the use of square brackets the most universally accepted and recognized method for referencing elements within an array.
